While Mitsubishi was unveiling the proto-Evo, Prototype X, at the Detroit auto show last week, over at the Tokyo Auto Salon it was teasing the crowd with a smaller-scale version of its earlier Evo concept, Concept X. Parked next to the concept was a tiny knockoff created by Kidzania Tokyo. According to Nihon Car and Bike, the company — an operator of theme parks for children that mimic adult living using downscaled props — says it's "drivable," with a real engine of some kind and four small seats. An Evo keicar? That's fairly brilliant.
